Electric power apparatus and installations
The subject area concerns design, dimensioning and modelling of electric power apparatus and installations such as high voltage switchgear and subsea power equipment. In order to develop good designs and solutions it is often necessary to consider electromagnetic, thermal and mechanical aspects in the design phase. This often necessitates the use of numerical software for design analysis and optimization.
